UHF/VHF HDTV Antenna

Lava UHF/VHF  Antenna

With over 1,000 stations in more than 200 markets broadcasting digital television, nine out of ten households can now receive free HDTV signals with the right antenna, a set-top box and a high-definition television. This Lava Electronics HD-2605 Remote Control HDTV Antenna features 360-Degree rotation to make sure you get the best HDTV reception possible. Its high sensitivity reception helps you get the weakest HDTV signals in more rural areas. These antennas are capable of receiving weaker HDTV signals when no significant multipath (ghost) conditions exist, i.e. no reflective structures nearby. 

Customer says about this products :

John S Pieri wrote : We get 22 channels and we are 80 miles from the nearest transmitters.All the channels are clear, crisp, HDTV national channels and a few local channels. Install took about 20 minutes after assembly.All we used was a Phillips screw driver. Once mounted, with the directional motor, we aimed it perfectly for best reception.The 30 feet of cable provides lots of options for mounting on your roof top.We really didn't even need a tall pole, but we put it atop a 10 foot one inch pole.This will work on your RV or boat too, it doesn't have to be mounted too high.Cable TV is fine, but this will pay for itself in one month, so we were sold.

Another customer wrote : 
We live 80 to 100 miles from any transmission towers which are in several different directions. After trying several so called omnidirectional antennas we purchased this antenna after reading reviews. The antenna is outstanding. It pulls in strong signals from all the closest towers and we even get some channels from areas beyond 100 miles.

Keep in mind digital signals are effected by severe weather much like the small satellite dishes so during bad weather we loose the furthermost signals and some of the closest ones come and go during the worst weather.

We have been through several mid-west severe thunderstorms since I installed this antenna and everything still works like it did out of the box.

Just an added note the antenna arrived too late to install out side the first night so I sat it on a table in our front window and got better reception with it there than we were getting with our other antenna mounted 50 feet high outside. This is truly a great antenna and I would strongly recommend it especially for anyone living in extreme fringe areas.

My only suggestion to the company is to include a direction indicator on the on the remote control and have directional buttons instead of double clicking to reverse direction.

The Wavelength of Frequency

The wavelength is proportional to the reciprocal of the frequency. The wavelength of any wave is related to the frequency so that fλ = v, where f is the frequency in Hz, λ is the wavelength in meters, and v is the velocity of propagation in meters per second (m/s). Because radio waves propagate at the speed of light (which is also an electromagnetic wave), approximately 300,000,000 m/s in both free space and the earth’s atmosphere, the lowercase letter c is used to represent velocity (rather than v), so you can rewrite this expression in the form :

f(Hz) = c / λ(meters) = 3 x 10^8 / λ(meters)

These equations are sometimes abbreviated for use with the units kHz and MHz:

F (kHz) = 3 x 10^5 /λ(meters)

F(MHz) = 300 / λ (meters)

You can get an idea of the order of length of these waves  for several different frequencies: 100 kHz, 1 MHz (in the AM broadcast band), 10 MHz (in the shortwave bands), and 1000 MHz (microwave bands). If you work the equations, then you will find that these wavelengths are 3000 m (100 kHz), 300 m (1 MHz), 30 m (10 MHz), and 0.3 m, or 30 cm (1000 MHz). You can see from these numbers why 1 MHz is in what is called the medium-wave band, 10 MHz is in the short wave band, and 1,000 MHz is in the microwave (“very small” wave) band. At 100 kHz, which is 0.1 MHz, the wavelength is 3000 m, so this frequency is in the long wave

band.

Ultra-Thin Indoor HDTV Antenna

There is no one magic antenna or antenna type that will deliver excellent TV reception in every
location. The main factors determining reception are the distance and direction from the TV
station transmitters to your home. Other factors include the transmitter's power and the height of
its tower, the terrain between the tower and your antenna, and the size and location of any large
buildings in the path of the transmission.
If you live within a few miles of the transmitter, and the signal path is relatively unobstructed,
you may be able to get adequate reception using a small set-top indoor antenna. But as you move
farther away, getting usable signal strength becomes trickier. This is where careful antenna
selection and installation become essential.
The information below will help you zero in on the type(s) of antenna that should work best for
you. Keep in mind that even in the same neighborhood reception conditions often vary from
house to house. For that reason, it's best to purchase your antenna from a dealer who offers no hassle returns with a money-back guarantee.


One of the good product recommend by customer reviews is Ultra Thin Indoor HDTV Antenna from AmazonBasics. These antennas coming with 4 types of model and range, from 25 Mile, 35 Mile, 50 Mile and 60 Mile. With 1 year limited warranty.  One of customer get almost 44 Digital Antenna channels found. This antenna for 50 miles range will worth your time and effort

Wi-Fi 2.4 GHz Antenna

The Speed of your wireless connection will vary depending on the strength of the signal you can receive and transmit. Antenna selection can therefore have a significant impact on the speed of your wireless link.

Types of Wi-Fi Antennas 

 There are two basic types of antennas for WLAN and cellular products :

Omnidirectional and directional. The two types are categorized by the direction in which they beam radio signals.

Omni-directional

Omnidirectional Antenna Pattern

Omni-directional antennas are designed to radiate signals equally in all directions. Use this type of antenna if you need to transmit from a central node, such as an access point, to users scattered all around the area. Omnidirectional antenna consist of 2,
Dipole antenna, and

Directional Antennas

 

Directional Antenna Pattern

TPLink Directional Wi-Fi Antenna

Directional antennas provide a more focused signal than omnidirectional antennas. Signals are typically transmitted in an ovalshaped pattern with a beam width of only a few degrees. With higher gain, directional antennas can also be used outdoors to extend point-to-point links over a longer transmission distance, or to form a point-to-multipoint network.

Antenna Connectors

N Type Female Connector

PRSMA Connector

MCX Connector

Before you purchase an antenna for your wireless device, you should check the type of antenna connector that your device uses. You will need to buy an antenna with a matching connector. There are several types of antenna connectors, including MCX, TNC, N-type, SMA, and RP-SMA (RP stands for “reverse polarity” or “reverse ping”). On WLAN devices, the most commonly used antenna connector is PRSMA and N-type for IEEE 802.11 wireless applications. Make sure you are buying an antenna with the right connector type.

What Negative Comment from Users about This Products ?

Some users convince that this antenna won't work for people who have their TV very fair away from windows. Because the length of the cables on the antenna are simply going to be too short for most people.  If your TV isn't within 2-3 feet of a window facing in the optimum direction, this won't work very well, if at all, for you.

The other major problem is that the suction mount for the antenna is pretty much worthless. It stuck on my window for approximately 15 seconds before falling off.

The antenna does work but you need to really be facing the right direction which can only be determined by trying it out. And the mount is really poor plus the short cables make it mostly unworkable for most people.

Another customer give negative comment about this antenna , "this antenna makes me really disappointed, also the amplifier makes the reception worse than better for most channels. My home is only 6 miles north from Seattle's downtown, using antenna only I can not get local channel 22, 33, 42, etc.; using "antenna + amplifier" I can get sort of reception on channel 22, but the same time worse reception on other channels."
Another customer said that this antenna  "It did not work. It did not increase my signal strength so I returned it "
